Introduction

This is just a quick guide on how I see Sejuani (The Boar).
I feel she is a very strong tank because of how effectively she can stop enemies from passing her, as well as her strong initiation powers.

I would not recommend playing Sejuani in the lane because a low damage melee champ with no shield or sustain is just asking to lose the lane.

You can go 0/21/9 or 9/21/0 but you do really need the 21 points in defence to jungle with an acceptable level of health

Skill Sequence

start with w as its your highest damage ability and will help you clear the jungle fastest, q second to apply the frost debuff in an AoE so that w does more damage. Q can also be used to jump over most walls which can help you reach camps faster.

You should have 3 points in w at level 5, this is because it is your main tool for clearing the jungle, 3 points wil give you respectable clear times. Afterwards focus on leveling e to rank 5 by lvl 10. I do this because the slow from e increases each level and the stronger the slow the better your ganking is.

Take your ult when ever possible :P

Jungling+Ganking

Skill Order WQWE

Wolves
Blue
Wraiths
Wolves
Golems, Then back

Wraiths
Red, Then Gank.

Ganking is pretty easy on Sejuani, use Q to close the gap and attack the enemy to apply your passive, (if it is bot lane try to hit both of them with Q to apply frost). Use e to lock down the target(s).

Your ult can be very useful if you walk into a skirmish in a lane, it has massive range so it is easy to catch enemies off guard with it. Everyone who is stunned by the ult has frost applied, but make sure to save permafrost for when they start running!

Items

The best start is regrowth pendant into philosophers stone, amazingly it feels like the philosophers stone makes up for the sustain Sejuani lacks. Wriggles is not required as she already does enough damage from W. You should get boots on your first back.

There are many build choices for Sejuani, remember to build according to your enemies.
I reccomend a warmogs in any build as core because her W ability scales off max hp. With the Hp from warmogs you are free to build staight resist items such as frozen heart and wits end (four stacks wits end give the same MR as a banshees veil). Youmuu's Ghostblade is a great all round damage item and helps to max out CDR and increase your champions threat level.

I think anything goes for Sejuani's items, as long as you have a good mix of health, and resistances.

The second build is a new build which I have had success with, I think it is because the core items aegis and guardian angel are cheaper and have more balanced stats

Summary

I am very greatful for anyone reading this and I hope you will consider some of my ideas, Thanks :)
